I'm jjust wondering if it's possible to get by without frost resist, i'm going in there tonight or tomorrow to main tank and i don't have the frost resist as of right now. Just wondering if it is going to be an issue.
If you have the avoidance/HP then no it shouldn't be a problem. If you don't, or your healers aren't very responsive to big spikes, then you may want to bring the FR gear, just in case.
As long as you have a CD for every frozen blow, only thing that will really kill anyone is getting hit by a falling spike or people are not moving to clear their debuff
I've never worn frost resist for Hodir-10 and usually don't pop CD's for frozen blows either. If you run into problems, a pally frost aura takes care of everything.
